HTMLCOIN is a new blockchain based on Qtum which uses Bitcoin Core and integrates Ethereum based smart contracts. It implements an extensible design which is capable of adding more VMs, enabled primarily through the Account Abstraction Layer, which allows for an account based virtual machine to function on a UTXO based blockchain.

This is a quick start script for compiling HTMLCOIN on Ubuntu

sudo apt-get install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils git cmake libboost-all-dev
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:bitcoin/bitcoin
sudo apt-get update
sudo apt-get install libdb4.8-dev libdb4.8++-dev

# If you want to build the Qt GUI:
sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler

git clone https://github.com/HTMLCOIN/HTMLCOIN --recursive
cd HTMLCOIN

# Note autogen will prompt to install some more dependencies if needed
./autogen.sh
./configure --disable-shared --enable-static 
make -j2

The commands in this guide should be executed in a Terminal application. The built-in one is located in /Applications/Utilities/Terminal.app.

Install the OS X command line tools:

xcode-select --install

When the popup appears, click Install.

Then install Homebrew.

brew install cmake automake berkeley-db4 libtool boost --c++11 --without-single --without-static miniupnpc openssl pkg-config protobuf qt5 libevent imagemagick --with-librsvg

NOTE: Building with Qt4 is still supported, however, could result in a broken UI. Building with Qt5 is recommended.

1. Clone the HTMLCOIN source code and cd into HTMLCOIN

    git clone --recursive https://github.com/HTMLCOIN/HTMLCOIN
    cd HTMLCOIN
   

2. Build HTMLCOIN CORE:

   Configure and build the HTMLCOIN binaries as well as the GUI (if Qt is found).

   You can disable the GUI build by passing --without-gui to configure.

   ./autogen.sh
   ./configure
   make
   

3. It is recommended to build and run the unit tests:

   make check
   

Then you can either run the command-line daemon using src/htmlcoind and src/htmlcoin-cli, or you can run the Qt GUI using src/qt/htmlcoin-qt

HTMLCOIN is GPLv3 licensed.

The master branch is regularly built and tested, but is not guaranteed to be completely stable. Tags are created regularly to indicate new official, stable release versions of HTMLCOIN.

The contribution workflow is described in CONTRIBUTING.md.
